A
Step-by-step explanation:
I tried my best to explain it...dm me if you still don’t understand
Hope this helped :)
Add the total of both groups and divide by the total number in each group
Group X = 535 / 18 = 29.72 mean
group Y = 500 / 18 = 27.78 mean
Group X has the higher mean
I think its 7x since x represents the hours she worked. So lets say that she worked for 5 hours this day. It would be 5*7 which is $35. So it is 7x and if there is any choices you might say it as well so we can help you better
We assume you want to know what Lamar should have written as the definition of f(x).
We know the points (-3, -2) and (2, 3) are on the graph. These differ in both the x-direction and the y-direction by 5, so the slope of the line is 5/5 = 1.
Since the line goes through point (-3, -2) with slope 1, we can use the point-slope form of the equation of a line:
f(x) = 1(x -(-3)) +(-2)
f(x) = x +1 . . . . . . . . . . after simplification
